the neck of a receptacle below its mouth and is formed of spring metal, would, if not prea sharp edge 3" to form a groove below the vented from spreading, separate to such an of the grafting-tool forced into the mouth of the receptacle, the forming-fingers 3 passing to the outside. If the receptacle is a bottle, the opening thereinto is smaller than desired; hence the necessity of the finger 12 to enlarge the opening'. The grafting-tool is now compressed until the forming lingers 3 bear against the outer surface of the neck of the bottle and either the bottle or the tool or both turned. The extreme end or mouth of the bottle enters the countersink in the roller 11, where the bead 25 on the bottle is formed, the groove 26 below the bead being produced by means of the sharp edges 8b on the formingngers. Other beads are produced by the grooves 3iL on the forming-fingers 3. `The bottle being in a soft putty-like condition the lugs 19 readily cut through the glass .when the end of the receptacle is pushed into the countersink 18, so that when the bottle is rotated the roller 11 turns with it. The amount of rotation must be sufiicient to complete the bead or beads and spread the soft glass into the countersink. After a bottle is finished, the forming-fingers are opened and the bottle withdrawn from thergrafter bya slight turning movement, which causes the lugs 19 in the countersink to form the angularv grooves 27 in the outer bead 28 of the bottle. To prevent the glass from adhering to the fingers 12, its flat sides 15 and grooves 16 are covered withamixture of rosin and charcoal. A portion of the same mixture is placed on the forming-fingers 3, and, if necessary, the countersink 18 may be so treated.

The roller 11 can without difficulty be applied to bottle-forming machines as well as to a hand-tool and will work with equal facility thereon. While I have shown but three lugs on the roller 11, I do not wish to confine myself to this particular number, as various changes may be made without departing from the spirit of this invention.

Having thus described the invention, what is claimedas new is- A tool for finishing bottle-necks and forming grooves therein inclined to the axis thereof, the same comprising vactuating-handles, forming-fingers carried by said handles, a support also carried by the handles, a fixed taf pered finger betweensaid forming-finger, said fixed finger being provided With a shank connected with said support and .having a shoulder at the base of its tapered portion anda journal between said shank and shoulder, and a forming-roller mounted on said journal and provided with an annular tapered recess opening through the front thereof, the inner wall of said recess projecting beyond` the outer .wall and mouth of said recess and forming with the inner rear wall of the roller a hub coextensive vin lengthwith the thickness of. the body of the roller and arranged for rotation on said journal, said hub having arforward extension therefrom engaging the. shoulder of the tapered finger, retaining the tapered finger beyond the recess and forming a shaping-surface and extended bearing, the outer .and shorter wall of the recess being formed withinthe recess with lugs having their sides inclined to the axis of said roller.

In testimony whereof I aflix my signature in presence of two witnesses.
